<p><P>PROBLEM TO BE SOLVED: To stably connect a battery and a tab even when a tab is made of a metal with low electric resistance. <P>SOLUTION: A thin plate-like tab 2 is located on an electrode 1A of a battery, and one of a pair of welding electrodes is a surface of a tab 2 and its tip is brought into contact with a first position 3. The other of a pair of the welding electrodes is inserted in a first escape hole 4 provided on the tab 2 and its tip is brought into contact with the electrode 1A of the battery. A pair of the welding electrodes are conducted, so as to weld a contact part to the electrode 1A of the battery on a rear face of the first position 3. One of a pair of the welding electrodes is inserted in a second escape hole 5 communicated to the first escape hole 4 provided on the tab 2 via a slit 6, and its tip is brought into contact with the electrode 1A of the battery. The tip of the other of a pair of the welding electrodes is brought into contact with a second position 7 bridging the slit 6 seen from the first position 3 on the surface of the tab 2. A pair of the welding electrodes are conducted, so as to weld the contact part to the electrode 1A of the battery on the rear face of the second position 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
